Application filed April 1, 19151 Serial No.

To all 'whom t may concern:

Be it known that l, BEN Bonanni, JOHN- soN, citizen of the United States of America, residing at 60G Cherry street, in Evansville,

s Vanderburg county, indiana, have invented -certain new and useful lmprovements in Sewer-Traps, of which the following is a specification.

-'l`his invention relates to sewer traps and lo particularly to means for preventing baci:

low of fluid from the sewer through the sewer trap to the place drained by the sewer trap, the saidzinvention being shown as applied to receive fluid from a street gutter l and the mechanism being adapted to prevent back iiow of fluid to the street level.

' A further object of this invention is to provide a sewer trap havingl means by which the iniloiving liquid may not be obstructed While, at the same time, providing,l means for closing the inlet passage should the pressure within the trap exceed the pressure of fluid running; into the trap.

A still further object of this 'invention is to provide a sewer trap operated by gravity to close the inlet and novel means detaehably connected to the sewer box for supporting inclosing medium, the said parts beingreadily removed for renewing Worn or impaired parts or for the purpose of gaining; access to the interior of the box.

With the foregoingand other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts te be hereinafter more fully setl forth and claimed.

ln describing the invention in detail, reference will be had to the accompanying drawings forming part of this specication,

4@ wherein like characters denote corresponding parte in the several vierge, and in Which- Figure l illustrates a. vertical sectional view of a server hor. and the masonry inwhieh it is embedded; i5 Fig. lll illustrates a line 22 or" Fig. l.

n these drawings sectional view on the i denotes a ,surface plate having' an aperture therein, the said plate having` a depending' flange B forming a seat for an aper ed cover B constituting a, vent :for the trap. The plate l rests on suitable masonry C which mail he concrete or other material for con ie; and supportingn the server hon il. f i ver box has an aperture into which the 'pipe D extends and the said pipe D is a conduit for the pas mma-mma atenten?. Aron ulti, 22,906.

The pipe ll is sage of fluid `into the trap.

trap by a chute D surrounded Within the having a flange D2 the said i'iange being secured to the sewer box by i'astenin'gs M, such as rivets or the like. @n the upper portion of the chute, l mount the brackets Gr, said brackets having lugs l, constituting bearings for the pins H, which pins entend through lugs H on the arms l, of the door said door having 'a handle L by which it is manipulated. The position of the supports of the arms li end or' the chute and the lovver wall of the chute extends outwardly slihtly beyond a. vertical line along the end or the upper portion of the chute. This relationfof parte is maintained ior the reason that the door to be operated by gravity to close the chute and any bach pressure or flow oil liuid from the sewer would aid in maintaining,` the door in such closed position, `whereas the door would 'be free to swing' open under pressure of fluid flowing into and through the chute. he sewer box has an outlet ll with a nine F, the

is slightly rearwardly of the l) leading'into the server, the said pipe extending through the masonry C, shown in Fig. l'. The door F has a gasket lf2 which bears against the end ofI the chute, thereby making a tight joint and insuring against liow of fluid through the opening guarded by the door.

l claim.M

1. A sewer non comprising Wall of masonry, a dis therefrom, a delivery pipe les mg thereto, a chute embracing1 'tn-e delive end of the delivery "pipe, meant- ;ior securing the chute to the said Wah,y s iorting members detachably connected te ie chute, said supporting' members having` "-,vardly inc-lined bearingM surfaces, a door tor closing the chiite, said door having` slotted arms to receive the supporting members., and members on the said arms the said supportingn members constituting hinge.

A server hof.: comprising an inelosingr Wall oi masonry, a discharge pipe leading;I therefrom.v a delivery pine leading` thereto, a chute embracing the delivery end of the delivery pipc and having;n its outer end beveled with its lower edge entendi? er hewnul upper edge forming an inclined door, means for securing the eh said Wall, supporting; members connected to the chute, said sapin v bers having' rearwardly inclined he an inelosingF hwg@ Pipe leading l faces, :t door foi" closing the chute, said door having relatively long slotted arms to receive the supporting members, and members on the said arms engaging the said supporting members constituting a hinge for the door.

In testimony whereof, I afx my signature in the presence of two Witnesses.
